How many can we fit in here?

Spent today at my friends house having a barbecue with all the gang (7 kids, 7 adult females).
The children were delighted to be let loose in the garden after being stuck inside for days with all the rain we've had here, and made the most of amusing themselves while us ladies got on with the gossip and baby talk (3 of my friends are patiently waiting the imminent arrivals of their babies).

I nipped outside before the buffet was put out and this is what I found.

6 of them had managed to squeeze themselves inside a tiny kids ball swamp. There was a bit of a struggle when the little Mia tried to get in which inevitably ended in tears, but not before I caught this pic!
